I've seen a few issues come up where users Zimbra calender is auto accepting invites. I WANT this to happen for a calender I want everyone to share. We use Zimbra Collaboration Suite at our school and as the IT department, we don't want to have to send out invites every year for new faculty/staff or students and then worry about them accepting these invites.

Basically, is there a way to push out or force a calender to all users on campus?
